Possible Duplicate:
Access GET variables with PHP + .htaccess

I am trying write a combination of .htaccess and PHP script to do the following:

If the URL = http://mysite.com/XXXXXXX
Redirect to http://mysite.com/subdir/index.php?var=XXXXXXX

Where XXXXXXX is any alphanumeric string 7 characters long without a .php extension.

This is what I have so far,

RewriteEngine On
RewriteRule ^(.*)$ index.php?code=$1
RewriteRule ^subdir/(.*)$ index.php?code=$1 [L,QSA]

Any help would be greatly appreciated.

UPDATE:
Thanks for the replies, the link helped but I think where I am having trouble is the condition.

RewriteEngine On
RewriteCondition [HAS 7 ALPHANUM CHARS]  <--HERE
RewriteRule ^(.*)$  /subdir/index.php?code=$1 [QSA,L]

Answer 1

Try simply:

RewriteEngine On
RewriteRule (^|/)([a-z0-9]{7})/?$ index.php?code=$2 [L,QSA,NC]

The regular expression (^|/)([a-z0-9]{7})/?$ makes sure to match the very last part of a URI, after the last / and having exactly 7 numbers/letters.

So these will match:

/123abcD
/123abcD/
/something/098eif2
/foo/bar/path/1q2w3rT
